Yeah, I'm talking about the aussie t-case gears. I know absolutely they'll fit the V4AW2 which went in many 1990-1994 3.0 trucks. I'm almost positive they'll go in the KM148 that went in many of the Gen1's to 1989. But I don't have any idea if they'll fit in the KM146 which went in some of the earlier Gen1's. No biggie, I'm putting together installation instructions for the 2.85 t-case gears and I wanted to list the transmissions they'd go in.
